I like my bass to have a little punch, but not anything too artificial. Are these a good buy, or the Planar HE4xx, or the 6xx? I currently am using Sennheiser game zero, and they don't have any punch at all. Bass is almost non existent.

Had these headphones for about 6 months or so. The right cup makes an annoying creaking sound, does it every time I turn. Annoys the heck out of me. I look at my HD598SE and wonder why AKG can't make something of quality like Sennheiser.

Well, I reached the 1 year anniversary of ownership about 2 months ago. Unfortunately, I have noticed that the sound in the right ear cup has started failing. Unfortunate, but understandable with this kind of headband design. Lasted less than both my ATH-M50x's and my V-Moda Crossfade Wireless' even through I was argueable rougher with those two. That said, the warranty for the K7XX is two years, so luckily it should still be covered. I'm am currently in the process of contacting AKG and will try to keep here updated on the warranty process.

P.S. Even with the negative comparison to the build quality to other headphones I've owned, it is worth mentioning that the warranty for the K7XX does have a two year warranty where the others only have a one year warranty.

for me, at least, I contacted Massdrop's support and explained my issue. Because they happened to have stock of the particular item they just shipped me a replacement pair. Entire process on my end took a little over a week.

Is this drop remaining active until an acceptable amount of units are sold? The drops has refreshed its counter for at least the past few days. Does that effect when shipments are sent out? I had purchased an AKG 7XX as a gift for an upcoming event and was hoping the estimated shipping time-frame was accurate so I could receive them before then, but it is behind schedule. Any ideas on a realistic shipping date?
